To all whom t may con/cern.-

Be it known that we, LUOIEN SCHMOLL and ARMAND SoHMoLL, both citizens ofSwitzerland, residing at Newark, county of Essex,

United States of America, have invented certain new and usefulImprovements in Polishing and Staining Machines, of which the followingis a full, clear,

. and exact specification.

Our invention relates to machines used for polishing, staining, andfinishing leather, wood work, or other similar materials, and has forits object, to provide a means for rapidly and thoroughly smoothing,polishing, staining and finishing such materials. We' attain theseobjects by use of the mechanism illustrated in the accompanyingdrawings, in which-- Figure 1 is a plan view of the machine. Fig. 2 is aside elevation of a part of the ma-4 chine, partly in section on theplane of the line 2--2 Fig. 1. Fig. 3 is a side elevationof another partof the invention, partly in section on the plane of line 3 3 Fig. 1.Fig. 4. is a longitudinal sectionof the mechanism shown in Fig. 3, andFig. 5 is a cross-section and end elevation of the universal jointmechanism on line 5-5 Fig. 3.

Similar letters refer to similar parts throughout theseveral views.

In the drawings, A is a table supported upon a suitable base or frame.Upon this table the material to be operated upon is laid.

B represents a movable cross-bar at or near one edge of the table andsupported by the frame by preference. By means of a leverC (3o-operatingwith toggle joints D D the cross bar B is moved toward a cross-barBfixed in the frame. Between these crossbars the edge of the material tobe polished is held. Although as shown and described the movement of thecross-bar B is horizontal, it would require only the skill of theordinary mechanic to adjust it so that the movement would be vertical. i

E is a shaft mounted in suitable bearings driving pulley G and also abeveled gear H. Upon the shaft .E is also a sleeve I free to revolvethereon,but not free to move laterally. This sleeve I loosely supports abearing pin J upon which loosely turns a second beveled gear K meshingwith the first beveled gear` The upper side of the beveled gear K isalso provided with beveled gear teeth which mesh with a third beveledgear L. This gear L is mounted around aslidin'g shaft M which passesthrough a bearing N at the top of the j `be in gear with the teeth onthe upper surface of the second beveled gear K. The third beveled gear Lis provided with a feather spline L2 which slides in a groove in thesliding shaft M, so that as motion is transmitted by power applied tothe driving pulley G and thereby to the various gears H K L, it will befurther transmitted to the sliding shaft M causing the same to revolve.end of the shaft M is fixed a beveled gear P. The end of the shaft Mloosely bears in a frame or case to which is attached a handle,preferably a `double handle asshown in Fig. 1. This frame or case adordsa bearing for another shaft which carries another beveled gear Q whichmeshes with the gear P'. To the lower end of the shaft supporting thegear` Q or to the lower side of the said gear, is fas tened by anysuitable holding device, a polishing stone R. In place of the stone, maybe substituted when desired, a staining brush or a box containing apolishing material.

It will be readily seen thatwith a machine so constructed, the polishingor staining agent may be tilted or moved to any part of thev tablewithin the radius of the sliding shaft M, this action being permitted bythe universal joint and the feather spline L2.

In operation thematerial to be operated upon is laid upon the table andclamped thereto. j The mechanism is then set in n10- tion and therapidly rotating stone is drawn over the surface until the suitablepolish is acquired. Stones of varying grain may be Near the outer IOOsubstituted one after another if desirable.

Instead of polishing the material, on the ta- Ils ble, it may be stainedby substituting a suitable brush containing the staining agent. In othercases the material may be both stained and polished.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

l. A polishing or staining machine, consisting of a table and arevoluble holder, said holder being mounted upon a revoluble andlongitudinally movable shaft, and free to be moved in all directionsthrough the medium of a double swivel joint at the point where the powershaft and longitudinally movable Shaft cross, with the gearing asdescribed, substantially as and for the purpose specified.

2. A polishing or staining machine comprising a table, a revolubleholder free to be moved in all directions, and actuated through themedium of the power shaft E, and sliding shaft M, as described,c0-operating with the said shaft E, through the medium of the'doubleswivel mechanism and the gears arranged contiguous thereto, all arrangedto permit universal action of the holder, substantially as described.

3. In a polishing or staining machine, the combination of a slidingshaft M supported by a double swivel joint, and therefore free to swingin all directions, and a holding device carried by said sliding shaft,with gears arranged around and contiguous'to said double swivelmechanism to transmit power from the power shaft to the said holdingdevice, substantially as and for the purpose described.

4f. In a polishing or staining machine, a powershaft supporting a doubleswivel joint, and a shaft M, supported in the head N of the swivel-pinJ, with a system of gearing H K L located around and contiguous to saiddouble swivel mechanism, the gear L carrying a feather spline moving ina slot in the shaft M, in combination with a revoluble holder located atthe end of the shaft L as described, substantially as and for thepurpose specified.

5. The combination in a polishing or staining machine of a table A,clamping device B B', with the universal joint H K L supporting alongitudinally movable shaft M by means of the bearing N, and with thefeather spline L2 on the gear L moving in a slot in the shaft M and withgear wheels P Q, and the polishing agentR all arranged substantially asand for the purpose specified.

In witness whereof we have hereunto set our hands this 22d day of June,A. D. 1894.

It is hereby certified that in Letters Patent No. 527,889, grantedOctober 23, 1894,

upon the application of Lucien Schmoll andArmand Schmoll, of' Newark,New Jersey, for an improvement in Polishing and Staining Machines, anerror appears requiring correction as follows: In the drawings thereference letter' I in Fig. il should be stricken out, the same havingbeen improperly inserted without the authority of the applicants; andthat the drawing and the patent should be read as herein set forth thatthe same may conformto the record of the case in the Patent Office.
